Description
FIELD OF THE INVENTION
[0001] The present invention relates generally to a location
tracking and communication system, and, more particularly, to a
system and method for tracking, maintaining, and communicating
exact locations of personnel at a real time basis, for
accountability, information, and decision making process
purposes.
BACKGROUND OF THE INVENTION
[0002] In times of catastrophic events such as earthquakes, floods,
fires, radiation/hazardous material leaks, and even the terrorist
activity as seen on September 11, when entire grids of power,
cell/telephone, electrical systems, communication systems, and
other internal systems/services to the structure and on the site
may be interrupted, pre-wired systems could also be damaged, and
further impede the progress of location tracking of personnel or
objects even though existing location tracking systems should be
present. In these situations, the first responder groups provide
law enforcement, safety, and protection services to the public. The
first responder groups include organizations and law enforcement
officers/personnel like police, sheriff, FBI, DEA, military
personnel, highway patrol, detectives, special law enforcement
groups, border patrol, firefighters, emergency medical services
personnel, Red Cross personnel, and other emergency workers.
[0003] The work of first responder groups is very challenging.
During the catastrophic events, the first responder groups have the
responsibility to respond quickly and effectively in order to save
life, property/assets of people. The life, health of personnel
responding to catastrophic events is always on danger because in
these situations, without an effective location tracking and
communication system, it is very difficult for the first responder
group to track exact locations effectively and quickly while
providing law enforcement, safety, and protection services to the
public. Therefore, it is very necessary for first responder group
to correctly identify and maneuver through the site (may include,
building structures and the like) efficiently, and also knowing the
structural integrity and material construction of the building, for
example, in strategic personnel extraction activities (usually
planned outside the site), if there is a choice between a steel
wall and a plaster wall, which should be used as an escape route.
Further, all stairwells, elevators, access point locations, and
possible exit points within the structure that could accommodate
basic duties, rescue operations, and personnel extraction, will be
evident on the architectural drawings and first responder group
should also have a system for real time ubiquitous communication
between all first responder groups.
[0004] Therefore, it is very important to provide enough real time
and accurate information to first responder personnel in order to
assist them in strategic planning initiatives so that they could
make more intelligent decisions before entering any structure
during a catastrophe or other event. Attempts have been made in the
prior arts to provide location tracking systems.
[0005] U.S. Pat. No. 5,793,882 discloses a personnel accountability
system that accounting for personnel reporting to a site. The
personnel accountability system includes an information receiving
device, a processor, and a display. The information receiving
device is provided for receiving information from a data storage
device carried by the personnel or from the personnel directly. The
received information pertains to the personnel, and may include
identification, qualification, and/or medical information. Upon
receiving the data, the system subsequently stores and displays the
received information. This system may also be used to receive
information regarding a site.
[0006] U.S. Pat. No. 6,750,769 discloses a method and apparatus for
using RFID tags to determine the position of an object. During
operation, the system receives signals from an array of RFID tags
at an RFID tag reader, wherein a mask of known size and shape is
interposed between the array of RFID tags and the RFID tag reader,
thereby obscuring signals from a subset of the RFID tags. Next, the
system determines the position of the object by analyzing the
pattern of obscured RFID tags, wherein the analysis is based on a
known spatial relationship between the object, the mask and the
array of RFID tags.
[0007] U.S. Pat. No. 6,854,010 discloses a centralized real-time
multi-location management system that manages the exchange of
location-level service data to a central server and also provides a
secure firewall for the location-level systems through a network
transceiver at each property. The network transceiver receives data
from the location-level service and transmits and receives the data
to and from the remote central server. At the central server, each
property's data are integrated into a central database for use by a
variety of central application services accessible by users through
thin-client user interfaces.
[0008] United States Patent Application No. 20050001720 discloses a
Firefighter Automated Accountability System (FAAS). This system
supports automatic tracking and limited communications among first
responders including fire, police, emergency medical service, and
safety personnel. The FAAS integrate wireless mesh networks with
positioning and communication systems to support real-time tracking
of and communications with emergency response personnel. The FAAS
incident awareness system provides position and time information
via Global Positioning System (GPS) and/or other positioning
systems, and processed data from sensors to provide enhanced
communications, command and control capabilities to the first
responders and incident command at the incident scene.
[0009] The prior arts/conventional systems have several limitations
and disadvantages. While accomplishing specific objectives, prior
arts do not provide adequate location tracking systems for: making
intelligent decisions regarding the specific structures for
deploying efficient activities within the structures; tracking and
maintaining locations of rescue personnel, at a real time basis,
for accountability, information, and decision making purposes; and
real time ubiquitous communications between all first responder
groups.
[0010] Therefore, there exist a need for a system for: tracking,
maintaining, and communicating exact locations of first
responder/rescue personnel at a real time basis; improving first
responder/rescue personnel safety and ability to fight the
catastrophic events/emergency situations more effectively by
providing adequate and accurate information to them so that they
could make more intelligent decisions before and after entering any
structure during a catastrophe or other event.
SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE INVENTION
[0026] The exemplary embodiments described herein detail for
illustrative purposes are subject to many variations in structure
and design. It should be emphasized, however that the present
invention is not limited to a particular system and method for a
real time location tracking and communications as shown and
described. It is understood that various omissions and/or
substitutions of equivalents are contemplated as circumstances may
suggest or render expedient, but is intended to cover the
application or implementation without departing from the spirit or
scope of the claims of the present invention.
[0027] The present invention provides a system and method for a
real time location tracking and communications (hereinafter
referred as the `location tracking system`) to track and maintain
personnel/objects locations within and surrounding building
structures or sites via real-time network for accountability and
informational purposes thereby allowing for cooperative measures,
ability to begin operations immediately, allowing for timely
response to a situation and better backup procedures.
[0028] The present invention find applicability preferably during
times of emergency, surveillance, or safety precautions (i.e. fire,
search and rescue, radiation leaks, Hazmat, etc.) and in times of
catastrophic events wherein electrical systems, communication
(cell/telephone) systems, and other internal systems to the
building structure may not be functional. Further, during natural
disasters such as earthquakes, floods, fire, and even during
terrorist activities the entire of power, cell, telephone, and
other services gets interrupted by the catastrophe. The location
tracking system 100 of the present invention supplies an answer to
this problem by using battery powered equipments and the ability to
set up and create ad-hoc networks fully functioning on power and
signals outside and independent of the primary systems used by the
building structure and its surrounding environment instead of
regular permanent tracking systems thereby reducing the cost of
installation of the system components substantially and more
specifically the power units which comprise a substantial element
of the system installation cost. Because of this independence from
structural amenities, the location tracking system 100 also allows
tracking and location to be attained within random structures (e.g.
abandoned warehouses, private residences, etc.).
[0029] FIG. 1, FIG. 1A, FIG. 2 and FIG. 3 explains in detail the
present invention and provides for a location tracking system 100
for tracking a location of objects (for example, personnel) at a
site (for example, in and around a building structure 110) in a
real time network through a communication network 120. The location
tracking system 100 comprises a central server 140; a plurality of
remote locator tags 160 disposed on said objects, a plurality of
remote repeater devices 180 (also known as `lunchboxes`); a
plurality of databases 220 connected to the central server 140, the
databases 220 having location information (i.e., having information
relevant to the location of objects, for example, blueprint
diagrams of the building structures 110 and the like, security or
fire systems, insurance related data, equipment related information
of the building premises, health related information of the
personnel, environmental related data, historical personal data,
information regarding citizens, and the like); a; and a processing
unit 260 with a tracking software operably connected to the central
server 140 through the network 120 to track location of objects at
the site.
[0030] The initial framework of the location tracking system 100
would be to configure a plurality of remote repeater devices 180
inside premises of the building structure 110 within which the
search or location operation would be undertaken. The repeater
devices 180 are transmitters capable of transmitting radio
frequency signals. In one exemplary embodiment of the present
invention, whether transmitting or receiving signals, the present
invention may use any operable radio wave frequency, which
includes, but is not limited to infrared, VHF, UHF, Bluetooth.RTM.,
Wi-Fi, 802.xxx, RFID, and ultra wide band (UWB) signals. This use
may be applicable for any component, including any transmitter,
relay, transceiver, or server, or a device that is capable of
receiving a frequency. The repeater devices 180 are capable of
receiving and transmitting signals to the central server 140 having
the plurality of databases 220 operably connected to it and to
which the processing unit 260 with which the tracking software is
connected. The repeater devices 180 may also include a large
battery (not shown) to allow the signal strength to be even greater
for penetrating deeper into the structure. The battery may be a
re-chargeable battery. The repeater devices 180 may further include
mini processor, a scale operating system, a port for
synchronization (USB, fire wire or others) if necessary to other
equipment, a software that will support the repeater devices' 180
operations and to upload or download media to and from the central
server 140. The size of the repeater devices 180 may vary and in
some embodiments may be as small as a palm pilot.
[0031] Pluralities of remote objects (personnel) with locator tags
160 coupled to them are sent inside the building structure 110. The
locator tags 160 (capable of transmitting radio frequency
identification (RFID)/ultra wide band (UWB) signals) have a size
that is small enough to be easily embedded into existing equipment
carried by the objects (personnel). Since the locator tags 160 are
small and lightweight, they do not add significantly to the weight
and volume carried by the objects (personnel), and thereby not
restricting any movement due to the locator tags 160. Further, the
locator tags 160 may be encased in an equipment to facilitate
constant usage. In an additional embodiment, one more advantage of
using ultra wide band UWB has also been found to have the potential
for streaming back thermal information for object tracking and
searches. If this is used in conjunction with this system, then the
information would have a high probability of being able to
assimilate these findings into the location tracking system 100,
and allow personnel that are not tagged to be tracked solely by
heat signature.
[0032] In an additional embodiment of the present invention if a
higher bandwidth version of RFID/UWB is used, first responder
groups 300 may also able to send back additional information across
the frequency in addition to location information. This information
may include, but are not limited to, health and system details of
the first responder group and equipment. Also with UWB and thermal
detection equipment, it could also be possible for the transmitters
of the first responder groups 300 to send back video and/or other
information that may be able to track and find objects that are not
tagged or connected to the location tracking system 100 for
search/rescue/recovery. Insurance information could also be derived
from this information if recorded or saved.
[0033] In one embodiment of the present invention, a minimum of
three repeater devices 180 are required for providing the three
dimensional location of the objects (personnel) with the locator
tags 160. However, the more the repeater devices 180, the better
would be the results and thereby the tracking capability. The
position of the repeater devices 180 are referenced to a static
known architectural point within the building structure 110 to
allow the location tracking system 100 and the tracking software at
the processing unit 260 to focus on that point as an initial
reference point. From that reference point, the tracking software
can calculate the X-Y-Z coordinates of the locator tags 160 in
reference to each remote repeater devices 180 to determine the
exact location of the object within the building structure 110 by
distances. These distances will then be correlated onto the
blueprint diagram in reference to the remote repeater device's 180
referential locations on the blueprint diagram to illustrate the
exact location of the object within the building structure 110. The
repeater devices 180 transmit RFID/UWB signals within the premises
of the building structure 110 and these signals are reflected back
by the locator tags 160 on the objects (personnel) which in turn
allow the repeater devices 180 to triangulate the object location
by the strength and direction of the received signal. Each locator
tag 160 on the objects (personnel) will provide a distinct static
ID or serial for the individual or object that it is coupled to.
The static ID would be the X-Y-Z coordinates in relation to a
particular repeater device 180. The locator tag 160 may also be
cross referenced to the objects that it is coupled to, i.e. if "Tag
1" is located on "Locator unit X", then the tracking software on
the processing unit 260 of the location tracking system 100 will
represent that "Locator unit X" is located where "Tag 1" is
located.
[0034] The tracking software of the processing unit 260 can compile
and assemble location information in the form of RFID/UWB signals
from locator tags 160 transmitted by the repeater devices 180 and
display the coordinates on a blueprint diagram of the building
structure 110. As used herein, the blueprint diagram refers to
technical drawings, architectural drawings and the like. The
processing unit 260 receives the blueprint diagram of the building
structures 110 from the plurality of databases 220 connected to the
central server 140. Data streams i.e. RFID/UWB signals should be in
a format that can be retrieved and assembled on the processing
units 260 of these systems, and display the necessary information.
In one embodiment, the tracking software will assemble RFID/UWB
signal transmissions from locator tags 160 transmitted by the
repeater devices 180 and place their location (i.e. the X-Y-Z
coordinates) on a grid that will coincide with the blueprint
diagram to precisely track the object inside or outside of the
building structure 110. The signals from locator tags 160 will
provide height and distance (i.e. X-Y-Z) coordinates for the object
(personnel) in relation to the repeater devices 180 and other
repeaters in time sequential data packets. If these repeater
devices 180 are in location that can be placed near an area of
architectural relevance (i.e. doors, stairwells, windows, or other
notable objects that would appear on a blueprint diagram), the
tracking software can assemble these coordinates and place them on
a grid that will coincide with their geographical location within
the blueprint diagram. If these areas do not exist in a building,
then an Ad-hoc setup should ensure where the distance and location
could be pinpointed by using the X-Y-Z coordinates of the location
of the locator units 160 (personnel).
[0035] The above operation of the location tracking system 100 is
described in terms of the process flow shown in flowchart 400 of
FIG. 4. The process begins with the installation and configuration
of the remote repeater devices 180 in the building structure/site
110, as shown in step 410. The personnel with locater tags 160
spread across the building structure/site 110. The repeater devices
180 transmit signals to the remote locater tags 160 disposed on
personnel at step 420. The signals may include, but are not
limited, to RFIB/UWB signals, and the like. The remote locater tags
160 reflect back the received signals from the repeater devices 180
at step 430. The repeater devices 180 thereafter send the received
reflected signals from the remote locater tags 160 to the tracking
software in the processing units 260 at step 440. The repeater
devices constantly keep transmitting signals within the building
structure/site 110 and the remote locater tags 160 also
continuously keep reflecting the signals back to the repeater
devices 180. The reflected signals from the locater tags 160
contain the coordinate information along with the time history and
the unique identifier corresponding to each locater tag 160, which
are forwarded to the tracking software at the processing unit 260
at step 450. The tracking software then calculates the exact three
dimensional location of the locater tag 160 based on frequency and
direction of the locater tag 160 from the distinct location of each
repeater device 180 at step 460. In one embodiment, it requires a
minimum of three repeater devices 180 for calculating the time
stamp of a locater tag 160. Upon calculating the location history
comprising the locater tags distance and location coordinates of
the locater tags 160, they are collected and assembled to represent
historical record of the locater tags 160 movement during an
operation and its usage at step 470. The relevant data of the
location history is stored thereafter for immediate "on-site"
retrieval or archival history illustrated at step 480.
[0036] All data could be assembled to incorporate any other
additional information that could be passed along the data stream
i.e. RFID/UWB signals from the object's equipment or other devices
within the building structure 110 that include, but are not limited
to, the temperature of the environment, the health status of
personnel, the air tank status of personnel, the hazardous
materials readings, the video surveillance, the video
communications and the location of non-tagged objects within the
building structure 110.
[0037] The historical data from a historical database 232 is
assembled by the software for future reference and data backup.
Suitable historical data for the location tracking system 100
include, but are not limited to, object location history, personnel
environment history, equipment history, and usage times. The
tracking software displays simultaneous floor plan and elevation
layouts of building. For example, as shown in FIG. 5, the tracking
software displays the building elevation showing the personnel with
the locater tags 160 spread out in different floors of the building
structure 110, and parallely showing the distribution of the
personnel with the locater tags 160 on a single floor of the
building structure 110. These views have the ability to be
manipulated to choose exact floor to monitor on which side of the
structure to view. This eliminates the potential to lose objects
i.e. the personnel that are stacked or in the same X-Y locational
coordinates but on separate floors or elevations. Also, the
tracking software is capable of containing blueprint drawings of
sewer lines (sanitary or storm), HVAC, electrical underground
cable, natural gas, corn lines (cable, telephony, fiber optics),
other gas storage or material of Hazmat consideration, and the
like.
[0038] The function of the tracking software allows the handheld
processing units 260 to look at the varying layers of the document
(i.e. floor levels, electrical, pluming and HVAC details), and
other information stored on the blueprint drawing. The location
tracking system 100 will supply two separate views of the blueprint
diagram, one that shows the elevation view, and allows the user to
turn and view the elevation from different angles; and a floor plan
view, which allows the user to scroll and select between the
different floors. Once the RFID/UWB signals from the locator tag
160 are plotted within the blueprint constraints, a user could
select the objects (i.e. personnel) via touch screens, function
keys, mouse, or cursors to view the details on that object or his
environment. These two separate types of resources may be tracked
on separate layers (or levels) of the location tracking system 100
to provide more efficient resource tracking on either level.
[0039] The object (personnel) will be displayed in a section of the
screen of the processing unit 260, showing vital information, and
the ID. The location tracking system 100 will prioritize object
(personnel) location in the list by their vital information (if
tracked), so if a person is low on air, their ID will be at the top
of the list to notify the managers that the individual will need to
be exiting the structure soon to refill or to rest. The personnel
IDs may be color coded on the screen to show different levels of
health or activity. Also, the location tracking system 100 may
allow the user to drill down on each personnel to obtain more
detailed data on that individual's status, equipment, or even
history.
[0040] By sing the blueprints diagrams of the building structure
110 and similar sites, the personnel may be able to correctly
identify and maneuver through the building structure 110
efficiently, and may have knowledge about structural integrity and
material construction of the building structure 110 to better plan
strategic initiatives. (Example: in strategic personnel extraction
activities (usually planned outside the structure), if there is a
choice between a steel wall and a plaster wall, which should be
used as escape route). Stairwells, elevators, possible exit points,
and the like, may be evident on the blueprint drawings. The primary
goal of the tracking software is to provide enough information to
first responder groups to make more intelligent decisions based on
real and accurate information before entering any site (for
example, the building structure 110) during a catastrophe or other
event.
[0041] The data streams i.e. the RFID/UWB signals will be
transmitted in time sequences that will show the object location
with a time/date stamp, which will be useful to track the locator
tags' 160 movement over time and distance. The result will be the
locator tags' 160 path for tracking purposes. These coordinates
will then be plotted onto a grid with the blueprint diagram of the
building structure 110, as a base. The tracking software will
utilize an object oriented database from the plurality of databases
220 connected to the central server 140, to store blueprint files
in their original or modified source code files. Other pertinent
information already collected on governmental or other databases
could also be "linked" or interfaced within the processing unit
260. This information may include items like registered pets,
registered health challenged individuals (who may be unable to help
themselves), owners of the building, and other necessary:
information.
[0042] In an additional embodiment of the present invention, relay
units 320 may also be either hardwired or retrofitted into the
building structure's 110 existing communication systems including
but not limited to electrical systems, protection equipment
systems, to ensure that signals from the locator tags 160 of the
objects (transceivers/receivers) are constant, and will not decay
or degrade within the confines of the building structure 110. More
specifically, in a site wherein the numbers of remote repeater
devices 180 are quite far apart and the objects with the locator
tags 160 are spread out, the reflected signals from the locator
tags 160 may not be strong enough to reach to the remote repeater
devices 180. Relay units 320 may also be necessary in dense
structures or areas where transmissions could be impeded by
environmental factors or physical material. These relay units 320
could either be wired into electrical framework of the building
structure 110, or they may also be ad-hoc arrangement, and may be
carried, and placed into use by personnel as they enter these sites
(the building structure 110). The relay units 320 are capable of
increasing the strength of RFID/UWB signals from the locator tags
160 and will allow the transceivers/receivers i.e. the remote
repeater devices 180 to get better location readings on the
objects, and they may also allow detailed data to be transmitted by
increasing the bandwidth strength of the transmissions.
[0043] In addition to remote relay units 320, it is also possible
to use hoses, and other equipment already entering the system to
house these ad-hoc relay units. By retrofitting or adding a relay
unit to the exterior of these equipment pieces, a relay network
could be created with little or no change in procedure from the
firefighting taskforce. Items like onsite hoses, fire pulls, and
fire extinguishers may be fitted with a battery powered relay units
that would be activated and powered when the items are deployed or
put into use (i.e. fire pull would also act as switch to power on
relay units to begin transmitting signals).
[0044] In another embodiment of the present invention, the location
tracking system 100 may integrate an active relay unit with a small
battery [not shown] to the emergency equipment systems already
existing in the premises of the building structure 110, that allows
the relay units 320 to be activated only when that emergency
equipment onto which the relay unit is integrated to, is triggered
(i.e. fire pull is pulled, or a fire extinguisher is removed from
its base). Also, because these safety items are regulated, and are
required to be checked and examined on a timely and periodic basis,
the relay unit and their batteries within these items would also be
examined consecutively. This additional point of security adds
another battery powered signal/repeater to be used in conjunction
with carrying and receiving signals within the structure, even in
catastrophic events. Insurance premiums could also be reduced for
structures that employ these devices, since they may be used to
minimize fatality risk, and will aid in tracking damage path within
the building structure 110.
[0045] If the building structure 110 is hardwired to have relay
units 320 and necessary equipment for personnel tracking within the
structure, and interfaced with other systems (i.e. smoke detector
systems, UWB environmental information systems), the first
responder groups 300 would have the necessary information to know
where the problem is, and be able to strategize more effectively
(based on amount of information available). When relay units 320
are hard wired into the structure and are integrated with a
structure's fire safety alarm, and sensor systems, the location
tracking system 100 can monitor any changes or distortions within
the building structure's 110 environment for insurance or personnel
safety purposes. However, for all pre-wired or hardwired systems,
there should also be a battery backup or the addition of battery
powered repeater devices and other signal equipment within safety
equipment to maintain transmission system integrity in the event of
power loss due to catastrophe. Suggestions for sites, like the
building structures 110 that should be pre-wired or hardwired
include schools, universities, stadiums, and other areas where
there are large amounts of patrons. Nuclear facilities, chemical
facilities, oil refineries, and other areas where materials on site
could pose risks to any personnel entering the areas would also be
locations where a hardwired solution is recommended. These
facilities and structures that would require Hazmat responses
should also incorporate battery powered sensors and detectors
(repeater devices) which could send signals to first responder
groups 300 to make them aware of potentially hazardous areas, and
to alert them to areas of contamination or leakage.
[0046] For structural fires, the transmission from the fire
detection system can track the path of the heat and fire. If
integrated into the system, this information would be useful for
personnel allocation, fire insurance analysis, material heat
resistance readings, possible cause and direction of fire, and
architectural response to catastrophe. The same is true of
structural collapse, when the relay units 320 can reveal which
areas collapsed at which moment using the historical tracking
features and gauging variations in location or displacement of the
sensors from their original positions. Also, when coupled with heat
sensitive equipment, and smoke detectors, it is possible to track a
fired weapon in a structure. This would be done by focusing
detection on the heat differential of the discharged weapon and the
environment. From here the location tracking system 100 could track
the path and location of the weapon across the blueprint
diagram.
[0047] If the building structure 110 is not pre-wired, then the
blueprint diagram would still be retrieved on a system used by the
first responder groups 300. The first responder group 300 would
then be dispatched with repeater device 180 (lunchboxes), and drop
them at architectural focal points (i.e. main doors, windows) for
the location tracking system 100 to gain locational bearing before
entering the building structure 110. The repeater device 180 would
send signals to be reflected off the locator tags 160, and then be
retrieved back by the repeater devices 180 to determine location of
the personnel. The information would then be transmitted from the
repeater device 180 to a central server 140 outside the building
structure 110 that would assemble the information, and detail the
locations in parallel, and in to the locations on the blueprint
diagram.
[0048] The processing unit 260 with tracking software (i.e., the
static local workstations or dispatch groups 380; or multiple
users/divisions 390) is connected to the central server 140 to
centrally support the operation of remote devices (i.e., the
locator tags 160 and the repeater devices 180), and allowing the
ability to upload or download signals to the remote devices. The
connection may be made through any type of known network including,
but not limited to, a wide area network (WAN), a local area network
(LAN), a global network (e.g. Internet), a virtual private network
(VPN), intranet or wireless networks, metropolitan area network,
future network configurations. The processing units 260 may be one
or more computing devices (e.g., a desktop, a lap top, a personal
digital assistant, tablet PCs, Transparent Systems, LLC mobile unit
PCs) or a more sophisticated device such as a server. In one
embodiment, the processing unit 260 is a Transparent Systems, LLC
mobile unit PC. In this embodiment, the processing unit 260 may
have a tablet PC with a liquid crystal display (LCD) screen and
handles housing a plurality of selection and function buttons;
wireless network card/network card to connect with LAN/WAN; and
other features of a regular computing device. The Transparent
Systems, LLC mobile unit is cased by a plastic sheet, such that,
all the buttons and the screen and the other functional features of
the Transparent Systems, LLC mobile unit will be housed inside the
plastic sheet and protected from unsuitable environmental
conditions outside. This makes the unit suitable for situations
where water, soot, debris, sand, and other materials that may
damage such units are present. In another exemplary embodiment, as
shown in FIG. 6, the processing unit 260 has handles 262 that are
disposed rightwardly and leftwardly of the processing unit 260 and
has a substantially curved contour. On the handles 262 are the
buttons 264 and a scrolling wheel 266. The buttons 264 can further
comprise separate button 268 for direction control and for
selection. The functions of the handle 262 can be tailored for
either right or left handed controls by selection of the buttons
264. In a further exemplary embodiment of the present invention,
the processing units 260 has a port 270 for charging of
rechargeable batteries, synchronization, and/or for information
exchanges, such as a Universal Serial Bus (USB) or Firewire
interface. The port 270 may be a PS/2 Port for a keyboard or mouse
terminal. Also, a barcode scanner 272 may be integrated so that the
remote processing unit 20 can scan barcodes.
[0049] The remote processing unit 260 may also be equipped with a
smart card slot 274, with a magnetic card reader operable with the
smart card slot 274 to read information from such devices as
driver's licenses, credit cards, or "frequent user" cards as part
of a restaurant's marketing campaign. Liquor stores or gun stores
may use to insert the drivers licenses of potential customers to
check for probation violations, or criminal records before
purchasing alcohol or guns, and also verify the authentication of
drivers licenses or other forms of identification. Border security
may use such processing units 260 to verify licenses, credentials,
or other forms of identification, and the same can be stored as
history of the persons in a particular locality. The information on
the processing unit 260 is displayed on the screen 276.
Furthermore, all ports or slots in the processing unit 260, in an
exemplary embodiment of the present invention, may have protective
airtight rubber (or other non-abrasive or oxidizing material) caps
or plugs that would be inserted in them when not in use, thereby
preventing damage to the unit through these access points.
[0050] A plurality of onsite responder vehicles 360 positioned near
to a site of incident, more specifically the likes of a fire/ER
vehicle which is capable of transmitting to the central server 140
is also connected to the same. Furthermore, organizations like the
fire department, police department or city hall may also be
connected to the central server 140 and forms an integral part of
the same.
[0051] The central server 140 has the plurality of databases 220
within its operational vicinity. Useful databases 220 for the
location tracking system 100 include, but are not limited to the
location database 222 for accessing location tracking information
at multiple locations, particularly, by the processing unit 260 and
the remote objects (personnel) at the building structure 110;
security or fire system database 224 having information regarding
the fire systems installed in the building structure's 110
premises; insurance database 226 providing details of the insurance
coverage of the equipment installations therein; equipment database
228 providing information regarding the various equipments
installed within the premises; health database 230 containing the
information regarding the health concerning details of the
personnel in operation; historical database 232 having personnel
history including location history, environmental history from
environmental database (what environments worked in), equipment
history and usage times, and the like, that may be used by the
location tracking system 100 along with the tracking software in
the processing units 260 for future reference and data backup; a
citizen's database 234 provides the full details of the citizens of
the locality; a map database 236 providing the map of the locality
detailing the various routes to and out of the locality in case of
emergency requirements; environmental database 238 (what
environments worked in); an object oriented database 240 housing
blueprint diagrams of the building structures 110 which is
connected to various architectural sources 242. The location
tracking system 100 further comprises a historical data backup
database 244 connected to the central server 140 for backing up all
the valuable information/data of all the above databases 220 that
may be used by the location tracking system 100 along with the
processing unit 260 with tracking software for future reference and
data backup.
[0052] The blueprint diagrams from the object oriented database 240
may be retrieved on external and/or internal processing units 260,
and on remote processing units as and when required. The tracking
software of the processing units 260 extracts the location data
thereby enabling better resource deployment, resource allocation,
resource proximity to emergency or danger areas, resource
extraction (injured, or need to evacuate quickly), resource history
for future reference, resource exposure to hazardous materials and
the like.
[0053] The processing units 260, i.e., one of the computing devices
stated above further has a plurality of ports or slots for
connecting additional devices or other equipment interfaces to a
primary module of the computing devices. The ports or slots of the
computing device have protective airtight rubber (or other
non-abrasive or oxidizing material) caps or plugs that may be
inserted into access points of these ports or slots when not in
use, thereby preventing any potential damage to the computing
device through these access points. The additional devices that are
plugged into the unit may have protective coating around insertion
point to prevent any material from seeping into the unit from the
device's point of contact with the port. Suitable additional
devices include, but are not limited to, USB or Fire-wire
interfaces to upload or download tracking information; battery and
related equipment, barcode scanners to scan equipment on site for
inventory purposes, magnetic card readers for driver's licenses
(possibly credit cards?) if device is interfaced with citizens
database 232.
[0054] The processing units 260 have handles to allow the user to
be mobile with the unit, and not confined to a seated or resting
position to utilize the machine. Function buttons are present on
the handles will allow easier access to the function keys, and
quicker response and usability for the user. Also, the computing
devices have scroll wheels to allow the device to scroll images on
the screen, or add future additional functions to the device;
thumb-pads on either side of the device to operate like touch-pads
on laptops or direction buttons on game controllers to move the
cursor. A mini joystick may be added to these thumb-pads to operate
in more of a joystick fashion.
[0055] The location tracking system 100 may be used by a variety of
first responder groups and other groups for to track and maintain
personnel locations at numerous sites/structures. Firefighters may
use the location tracking system 100 mobilize outside and inside of
random or pre-wired structures. Also, the location tracking system
100 may be used transmit other information such as video and health
stats back to the central system for maintenance and strategy.
[0056] Further, hospitals and other health centers may use the
location tracking system 100 to track patients who are not allowed
to leave restricted areas (i.e. dementia wards, nurseries), and
also to track medications and equipment to ensure that the items
are not stolen.
[0057] Further, amusement parks, gardens, and the like may use the
features of the present invention to track the location of lost
patrons, or prevent kidnapping. Children may be given locator tags
160 (for identification) when sent into the park, and the system
would track their locations by use of towers installing components
of the location tracking system 100 located around the park.
Moreover, by incorporating a wireless network in the park, the
information may be passed along the wireless network and
transmitted to the devices worn by patrons. Also, the amusement
park administration may place transmitters at each ride which would
provide the geographic area focal points and allow the tracking
software to position and place patrons in real time, and with
accuracy.
[0058] Further, nuclear facilities/nuclear plants may use the
location tracking system 100 within the existing framework of
equipment the nuclear facilities/nuclear plants. Normal employees
in these facilities are required to wear radiation sensitive
equipment to measure the amount of radiation an employee is in
contact with during a specified amount of time. By placing locator
tags 160 in such equipments, or using the locator tags 160 and
remote repeater devices 180 in conjunction such equipments, the
nuclear facilities/nuclear plants not only track how much radiation
an employee has been in contact with, but also area where radiation
leaks may be occurring. For example, the location tracking system
100 will track the geographic location of the employee during their
shift along the nuclear plant's blueprint diagram. If abnormal
radiation readings occur on their personal sensors, the location
tracking system 100 may track areas where the employee had been.
Also, if another employee had strong radiation readings, the
tracking software can track back both employees' tracks to
centralize the highest probability areas of where radiation leaks
may be occurring. This may be done by finding areas where both
workers paths crossed or where the proximity was close. This
ability to pinpoint the radiation will give the nuclear
facilities/nuclear plants better reaction time for timely repair of
radiation leaks, for better tracking ability of radiation levels
within the nuclear facility/nuclear plant for environmental
concerns, and for better tracking of employees when inside the
nuclear facility/nuclear plant to promote homeland security.
[0059] Further, the location tracking system 100 may be used for
tracking criminals/offenders by using the location tracking system
100 as a tether-like device. When inside a building or facility
that is hard wired for the location tracking system 100, the
whereabouts of the criminal may be tracked at all times; and when
outside a building, the location tracking system 100 may be
possibly sensitized to respond and give locations to cell towers,
and other local equipment to cannibalize their bandwidth and send
signals back to probation officers or police personnel. For
example, when a criminal enters an area that they are prohibited
from, an alarm would sound, and authorities would be aware of the
intrusion or violation of order, for example, when an offender
comes within a predefined range of a school or area where children
are playing; or in this case, where a child is abducted from a
known location, the tracking software may pinpoint the exact
whereabouts of all tagged offenders that were in that area, at that
specific time; or when there is violation near a school, an alarm
may sound within the school administration to notify them that a
potential breach has occurred near their facility. Also, the
location tracking system 100 may be used for placing a restraining
order on an individual. In violent cases, the victim who issued the
complaint may be given a receiving device that will alert them when
the individual is violating the order. In cases where the
restraining order is for a facility, the facility security or owner
may be notified that a breach or violation has occurred. In cases
where the nonviolent criminals are placed back into society, they
may be tracked continuously by law enforcement authorities of the
individual's location at all times. This may alleviate prison
overcrowding for governmental cost control, provide assistance to
probation officers to track down parole violators, and would
eliminate the need for archaic tether systems a wide area network
could be established over a geographic location to track these
devices (either through satellite, towers, and transmitters placed
intermittently in local areas). Also, the bars may be equipped with
the location tracking system 100 to announce the presence of
habitual abusers that drive under the influence.
[0060] Further, EMS drivers may use a scale version of the location
tracking system 100 to make their response time more efficient.
When responding to an emergency, the EMS drivers may retrieve the
information from the database regarding the location, and
architecture. For example, apartment numbers may allow the EMS
responders to be informed ahead of arrival of the exact location of
the apartment and thereby result sin following features and
advantages: EMS drivers may position their vehicle in the best
possible location for client extraction; EMS drivers may be
informed of stairwells and other architectural features; EMS
drivers may possibly know the location of on-site Automated
External Defibrillator (AEDs) or other equipment that could be of
use; allow them to be more efficient in which material and/or
equipment to bring to the emergency site; and hasten response time.
All of above features would result in time efficient and cost
effective processes for the EMS units.
[0061] Moreover, the location tracking system 100 may be used by
bomb detection and removal personnel. When responding to an
emergency, they would retrieve the information from the location
tracking system 100 regarding the location, and architecture, i.e.,
the location tracking system 100 may allow bomb unit responders to
be informed ahead of arrival of the exact location of the devices
and thereby result in following features and advantages: can
position personnel, vehicles, and equipment in the optimal
locations for bomb extraction and defusing; bomb detection unit may
be informed of stairwells, sewage pipes, gas lines, and other
architectural features; may mobilize their robotic units, track and
guide them with the location tracking system 100; may be aware of
structural impacts of blasts, and potential areas to avoid bomb
placement to mitigate damage to the structure or architectural
bearing points (this would mitigate loss of life, loss of
materials, or potential damage that could compromise the structural
integrity of the structure). All of above features would result in
time efficient and cost effective processes for the bomb detection
units. Also, these features would mitigate insurance damage
potential.
[0062] Also, the location tracking system 100 may be used by city
planners and developers. They could retrieve information from the
databases in the location tracking system 100 regarding the
location, architecture, and structural history of buildings and
such information may help in planning enhancements or
reconstruction efforts for buildings. The city planners may examine
how certain structures, materials, and architectural features
handle the local environment or catastrophic events. Such
information may also aid in determining if buildings have
compromised structures and whether they should be eliminated. If
the building could be eliminated, they could choose the best areas
to insert demolition equipment to pose minimal external threats to
surrounding structures and the environment. They would be informed
of the internal architectural features, gas lines, sewage lines and
potential areas that could create larger problems, and would allow
them to be more efficient in which material and/or equipment to
bring to the emergency site. Also, such information would allow
them to better plan city resources, and utilize existing structures
and buildings more effectively; and would allow them to have
information on all structures in the area to analyze, and study for
future planning efforts.
